how to clean roof lights?

How To Clean Roof Lights

If you have existing roof lights or perhaps you’re about to have them installed, it’s important to know just how to have them cleaned, even if you wouldn’t be doing it yourself. Generally, glass roof lights fitted in flat roof applications are more likely to be a major victim of staining and discolouration by several elements like rainwater, bird droppings, vehicle exhaust pollutants as well as tree sap. Therefore, just like any other parts of your home, periodic inspection of the units as well as regular cleaning is highly advised to help maintain their top performance for a lengthy period of time.

Firstly, when installing the roof lights, it’ll be helpful if its fitted at the right pitch so as to help keep the exterior clean as it enables the elements such as rainwater to run off the surface naturally. Cleaning roof lights involves working at height which can be very dangerous. Therefore, if you lack the skill and confidence to pull this off, it’s advisable to hire the services of a professional who can guarantee the best results for help. In this article, we aim to give you a good insight into how the roof light cleaning process works. Let’s have a look!

Rooflight Interior Cleaning

✓ Spread plastic under the roof light to catch dirt and spills

✓ Dust to wipe clear all loose dirt and cobwebs.

✓ Use a squeegee with a warm soapy water or any other glass cleaning product to clean the glass ( steer clear of any harsh chemicals or abrasive cleaners)

✓ Dry the roof light with a soft and lint-free cloth.

Rooflight Exterior Cleaning

✓ Access the roof safely with a specialist ladder

✓ Put mild detergent into a bucket and carry up to the roof before filling with warm water from a hosepipe

✓ Use the soapy water and a non-abrasive cloth or squeegee to clean the roof light, its surroundings as well as fixings.

How to fit a Velux window?

Velux windows actually refer to one brand of roof window, which are windows that sit in your roof space and allow light and ventilation into your loft. But how do you install a Velux window? If you’re a competent DIYer, it’s not as difficult as you might think.

You can normally install roof windows entirely from the inside, so you don’t need to get up on your roof or hire costly scaffolding. They come with detailed installation instructions, so as long as you follow them you shouldn’t have much trouble.

Before you start, you’ll need to read up on the Building Regulations and Planning Permission laws. Speak to your local Building Control department if you have any questions.

Firstly, prepare the opening by removing enough tiles or slates from the roof. There’s no need to go out on the roof – access them by cutting away the felt underneath which will give you access to the tiles and battens. Cut away one of the battens from under a tile, then you can slide all the tiles into the roof space. You’ll need to cut away the roof timbers to make the right size opening, then add more timbers to strengthen the ones that are left.

Next, remove the opening sash from the new roof window then fit the frame into the new opening using the brackets provided with the window. Then fit roof flashing between the new window and the roof so you don’t get any leaks. Then lay your tiles back in position around the new Velux window; you’ll probably have to cut some to shape which you can do with an angle grinder. Always cut them on the ground, not in position on the roof.

Lastly, fit the sash back onto the window and you’re done!

If this sounds like too much hard work, plenty of window installers will be able to help you fit a Velux window and will probably be able to provide a much cleaner finish.

will my roof leak with missing ridge tiles?

Will My Roof Leak With Missing Ridge Tiles?

Your roof is the first line of defence against the elements. Therefore, if you want your home protected at all times, there’s a need to ensure a professional inspection of your home at least once a year. However, there are certain issues that you do not have to wait for a professional to be able to spot by yourself. And an example of this includes a missing ridge tile. This issue is noticeable from the ground level while some tiles may even fall off and notifying you in the process. If you’re currently facing this kind of challenge, you’d probably want to know if the missing ridge tiles can cause your roof to leak. In this article, we aim to answer this question and more. Let’s take a look!

Firstly, there are a number of causes of missing tiles or slates and the most obvious is the weather. When the wind or rain gets very high, it can pull your tiles out of place and even more more, if they weren’t properly installed in the first place. Secondly, there’s also a chance that the nails may wear away. These are the nails that holds your ridge tiles in place, they can rust and wear away, hence leading to missing ridge tiles.

Therefore, the short answer to the question is yes, missing ridge tiles can cause your roof to leak. Even if it doesn’t leave a visible gap in your roof’s covering, it’ll create a break in the roof which weather can easily penetrate. And allowing this to happen makes the other tiles more susceptible to damage which won’t be good for the entire house as well as your pocket. Hence, once you notice a missing ridge tile ensure to have it replaced as soon as possible.

How to clean Velux windows?

Velux windows, or roof windows, are very easy to clean. Regular cleaning helps to keep them looking bright and shiny for years to come. So how should you clean Velux windows?

If you want to clean the air filter, you can remove it and wash it with your normal household cleaners. Velux windows have a cleaning position, so rotate and secure it into this position then remove the filter. You should be able to buy new filters from the manufacturer of your roof window.

To clean the outer pane, there’s no need to lean out of the window and risk falling out. Simply rotate the sash (the opening part) 180 degrees and secure it into position. Then you can clean the pane with a soft, lint-free cloth, sponge or squeegee and clean water. If you live in a hard water area, add some detergent to the water and wipe the window dry when you’re finished. You can also use normal non-abrasive household cleaners.

It’s recommended that you clean the flashing around your roof window at least once a year. You can use a brush to do this. This will allow rainwater to flow freely and stop any leaves from collecting.

If you’re in any doubt about using certain cleaners on your Velux windows, get in touch with the manufacturer who should be able to help. You can also do a patch test on an inconspicuous area if you’re unsure.

How can I maintain my flat roof?

You should inspect your roof twice a year, ideally after rain or snow, to see if it’s draining properly. Also in the Spring to check for damage that may of been caused over the winter months that will need to be put right before the next winter. Have an inspection carried out if you are unsure.

Can I change a metal roof to tile?

The feasibility of this will depend on the roof’s strength, in particular its load bearing capabilities. This is simply because tiles are heavier than the metal sheeting. Normally a tiled roof will need to take a load capacity of 60kg per square metre. You will need a trusted roofing company to advise on this.

What is a Velux window?

A Velux window is a brand of roof window, but the brand is so popular that people often use the name to describe the entire type of window. They are windows that are installed at the same orientation and ‘in plane’ with the surrounding roof, and they’re usually installed at a minimum of a 15-degree pitch. You can buy roof windows that offer completely frameless internal views for a really clean look in your loft conversion, while some come with built-in shutters.

Velux windows aren’t to be confused with rooflights which usually refers to a glazed unit that’s installed on a flat roof. It might also mean a window that’s been installed on a pitched roof out of plane with the level of the tiling.

People also confuse roof windows with skylights, which normally can’t be opened or closed and are usually smaller than Velux windows. Skylights, therefore, only let daylight into the room whereas roof windows also help with ventilation.

If you’re using your loft as a room in your home rather than simply for storage, you must have a roof window installed. Skylights won’t be enough as they don’t allow for ventilation. It doesn’t have to be a Velux window – it can be any type of roof window. Luckily, they tend to come in standard sizes and they must be CE marked if they’re sold as a roof window, so they should be easy to find.

How to repair flat roof blisters?

Blisters are most common on membrane roofing systems. Lots of contractors will tell you that if there are no signs of further damage, there might not be any need to repair flat roof blisters. They form when pockets of air or water get trapped between layers of the roof’s membrane or between the membrane and the frame. When the sun is out and it heats the pockets expand and stretch the membrane. If you do want to repair your flat roof blisters, there are a few ways to go about it.

If you have a membrane flat roof, cut away the membrane until you reach a place where the membrane is still stuck tightly to the roof. Reapply as many new membrane layers as you cut away over the blistered area. You might even need to do more. To make sure your patch remains watertight, you’ll need to leave at least 6 inches around the edges of the blister.

If you’ve got a felt roof, you can cut an X shape through the blister. Peel back the triangles that you’ve made and let the timber frame dry for a while (so don’t do this when rain is forecast!). Then, coat the area with lots of bitumen adhesive and leave it to dry until it feels tacky. Then press down the triangles of felt firmly into the adhesive.

After that, you’ll need to add more bitumen adhesive to the cuts you made. If you’ve got any spare roofing felt, cut a square that’s about 100mm bigger than the cuts then lay this over the adhesive. If you’ve not got any felt, it’s cheaper to use a self-adhesive flashing strip. Once you’ve laid the strip or patch over, seal the edges with more bitumen adhesive.
